Is there a way to use VB.NET to close MessageBox controls created by JavaScript in VB.NET webbrowser?
I do not want to disable JavaScript in the webbrowser, just to close the MessageBox controls (like clicking their "X" button). I could not get help from search engines. Help appreciated.
Vb.net is serverside and rendered before javascript as the javascript is client side and rendered on browser. So there is not such way closing alert pop up via server side code.
Neither it is possible via jquery on client side

I have a database in which users enter a value into Textbox1 on a form; the form also has an ActiveX Web Browser control (acxWebBrowser1), plus another blank Textbox2, and finally a command button. After the user enters text into Textbox1 and clicks the command button, the VBA code will navigate to a specific web page in acxWebBrowser1, enter the Textbox1 value into the web page form, and then obtain a result in the web page in acxWebBrowser1. The result is then grabbed by the VBA code and entered into Textbox2 on the database form.
What I need to be able to do is hide the ActiveX Web Browser control to (a) prevent the user from messing with the web page, and (b) to prevent the clutter and distraction of the ActiveX Web Browser since the VBA code does all the necessary interactions with the web page behind the scenes.
Problem is, I cannot get the acxWebBrowser1 to stay hidden behind a rectangle box control on the form because the browser automatically moves itself to the top of the stack of controls. If I reduce the size of the acxWebBrowser1 control to be very tiny, the web page does not function properly. If I make the web browser control not visible, then the code cannot grab the needed values. I cannot use a POST approach to avoid using the web browser. (I might be wrong about not being able to use POST--maybe someone can point me to how to do that if that is the way to go.)
How can I hide or put something on top of the web browser control?
Three hours later, it dawned on me how to accomplish hiding the ActiveX Web Browser but still get it to be accessible to the VBA code. Simple: Don't update the screen when running the code to access the ActiveX Web Browser and use the .Visible property to "show" the Browser Control when VBA needs to access it (but it won't be visible to the user if screen updating is off) and then hide the Browser Control when VBA is done accessing it.
Here's the code I used to accomplish that:
Application.Echo False 'turn off screen updating
Me.acxWebBrowser1.Visible = True 'make web browser control "visible" to VBA code
{do stuff, like: process web page}
Me.btnClickMe.SetFocus 'set focus on the button so we can hide the web browser control
Me.acxWebBrowser1.Visible = False 'make web browser invisible so user is not distracted
Application.Echo True 'turn screen updating back on
Me.Refresh 'refresh the screen; this is probably not necessary
Just be
absolutely sure to turn screen updating (echo) back on
You should send any error handling to code that sets Application.Echo True otherwise you will not be able to see or do anything if the code crashes after setting echo to False.
Am using vb.net in asp.net to create my project. I use also a bootstrap modal to get data from client.
In the modal I have buttons and textboxes that get the data from user. there is a FINISH button that ends the process and closes the modal
the problem is that the other buttons are not supposed to close the modal, but make some calculations and processes. At one hand I need the postback in order to tiger the events of the buttons, And at the other hand the post back closes the modal, and i have to re-open it at the end of each process. This action makes the modal close and re-open after each click, and it is not Nice or Convenient
I thought that if I disable the postback of the buttons, and use the OnClientClick to catch the client click, this will work for me. But the Question is how can I make the OnClientClick Call a server side code (Sub)?
Any other Suggestions are welcome :)
OnClientClick is just that the CLIENT CLICK it doesn't translate into a server side method. Each ASP.Net server control has an OnClick event which is associated with a server based method, but that would give you the exact same scenario that you're dealing with now.
In this situation, I would have the secondary buttons (i.e. the ones that don't close the modal by behavior) use AJAX to send/receive data from the server (accessing an ASHX file or some other handler/WebAPI). This removes the entire postback situation entirely which sidesteps the issue.
I've been trying to figure out the ID of a button on a webpage in the VB webbrowser, but as VB uses an outdated web browser so the webpage loads differently to chrome so I can't figure out what the ID of the button is.
Is there any way I can get the ID of a focused element with some code?
Or alternatively, what web browser does VB use, so I can do figure it out manually.
Thanks!
I am currently trying to use a web browser created dynamically in code to extract details in a web page, but I am unable to know when the load is complete. I know there is a .LoadCompleted event.
I tried it and it is not firing for some reason, so I dropped it.
But I am kind of looking for the type where we used to do for winforms webbrowser control. I'm checking if the document is ready like this:
Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete
Application.DoEvents()
Loop
Is there anything similar? So that I can check and continue with the rest of the code.
Make sure your web browser control is visible. Some events may not fire if the web browser control is hidden.

I am opening a web site in a vb.net 2008 webbrowser control. I want when I open the 3rd page of the web site then after the page is loaded , control focus programmatic-ly by Triggering TAB keypresses automatically by my code . Please tell me the solution to shift the focus control ?
I don't know if I have understood your question right, but you could try the following,
Keep track of whether you are on the third page in your web-browser control. If you are, you can execute a JavaScript function, which changes the focus of the text-fields.
Page.ClientScript.RegisteredStartUpScript(GetTypeOf(), "function_change_tabs", script, True)
